In the statement regarding outlier we have to fill "most" to complete the statement.

Given An outlier is a data value that is numerically distant from_________ of the other data points in a set of data.

We have to fill the blank. We can fill " most" in the blank.

If a number in data is more than 1.5 times the length of the box away from either of the upper and lower quartile of the distribution then that number is said to be an outlier.

There are two types of outliers: upper outliers, lower.

If any values in the data set are greater than the upper boundary then those values are the upper outliers.

If any values in the data set are less than the lower boundary then those values are called lower outliers.

Lower quartile = $Q_{1}-1.5*IQR$

Upper quartile= $Q_{3}+1.5*IQR$

Hence we have to use most in the sentence to complete it.

The digits of a two-digit number sum to 8. When the digits are reversed the resulting number is 18 less than the onginal

polet [3.4K]

Answer:

Step-by-step explanation:

Given: The sum of two digit number is 8

Reversing the digit will get us number 18 less than the original.

Lets take x as tenth digit of our number and y as unit digit of our number.

As given sum of digit is 8

∴ $x+y= 8$

∴ $y= 8-x$ - equation 1

We also know that reversing the digit will get us number 18 less than the original.

∴ $10y+x = 10x +y-18$

Now, lets put the value of y from equation 1

⇒ $10(8-x) + x = 10x+ (8-x)- 18$

⇒ $80-9x= 9x-10$

⇒ $90= 18x$

∴ $x= 5$

Next, substituting the value of x in equation 1

$y= 8-x$

⇒ $y= 8-5 = 3$

∴ $y= 3$

∴ The original number is 53, sum of the digit is 8 and if we reverse the digit of the number, we get 35, which is 18 less than the original number.

C. Explain why 32 percent is equivalent to

11Alexandr11 [23.1K]

Answer: 32% is equal to 32/100.

Step-by-step explanation: This is because 32% is also equal to 0.32. Percents are evaluted with the fraction denominator 100. 32/100 is also 32 parts out of 100 parts. This expression represents 32%.

10. Amina is currently twice as old as her younger brother,

maks197457 [2]

Answer:

When Amina is 18. Saad would be;

k. 14

Step-by-step explanation:

Let "x" represent Anita's current age and let "y" represent Saad's current age, we have;

Anita's age = 2 × Saad's age

Therefore;

x = 2 × y...(1)

In 4 years, we will get;

x + 4 = 1.5 × (y + 4)...(2)

Substituting the value of x in equation (1) into equation (2), we get;

2·y + 4 = 1.5·y + 1.5 × 4 = 1.5·y + 6

2·y + 4 = 1.5·y + 6

2·y - 1.5·y = 6 - 4 = 2

0.5·y = 2

y = 2/0.5 = 4

Saad's current age = y = 4 years

From equation (1), we have;

x = 2 × y = 2 × 4 = 8

Amina's current age = x = 8 years

When Amina is 18, we have;

18 = 10 + 8 = 10 + x

Therefore, Amina would be 18 in 10 years time from now, from which we have;

Saad would be 10 years + y = 10 years + 4 years = 14 years in 10 years from now

Therefore, when Amina would be 18 years in 10 years from now Saad would be 14 years.
